1 all whom ci'mg concern 'Be it known that I, (limo): W. Bunn /mu,a'fcitizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsyl inia, have invented certain new andusefui improvements in Cable fih'ipports, of which the following is aspecification. i

This invention relates to improvements in cable supports adapted to hehung at intervals upon a supporting or inessenger wire to receive andsupport. a cable therein, the messenger wire being formed of a pluralityof strands twisted around a central or core ll strand and providing themessenger wire with relatively -.large and small diameters .J inalternate succession, forming intermediate shoulder portions. 7 The obectof the invention to provide a cable support of novel, simple andeflicient construction \vli unis}; he iOIIllGt'l of a single piece ofspring wire and which has provision: first, whereby shoulder portions ofthe messenger wire may be utilized to prevent displacement of the cablesup-port longitudinally thereof; in aconstruction emiploying'ihooks toattach the support to the "messenger wire, without requiring a springpressed gripping of the hooks against the messenger wire to prevent thehooks from leaving it while a cable is being drawn through the support;sec-0nd, whereby the cable support may be constructed of a relativelyshort length of wire and possessmany advantages in its co-operation withthemessenger wireto prevent displacement thereon not possessed by priorconstructions which do not require a greater length of wire, therebyresulting in 'a greatsaving of material in. wire cable supports now ingeneral use; and, third, whereby many advantageous results-are attained.

The invention consistsdn the novel construction, combination 'andarrangement of parts hereinafter "escrihed and claimed.

In the accompanying drawings, illustrao in my invention, v

igure l is a transverse section through a supporting or liuess ;er wirehaving :1 cahle support applied viereto embodying my invention.

of themessenger wir Referringto the drawings, designates the supporting;or messenger. wire which comprises a central or core strand 3 and sixouter strands 6 lying side by side nndf twisted in. spiral form aroundthecore strand 3, as clearly shown in the drawings.

A messenger wire of tively large and sms this character has rela- 11diameters, which occur in alternate succession longitudinally'o'f thewire, as indicated at 7 and 8, respectively, in Fig. 2, and whi 111spiral form around the wu'e 2'fr0m end ch extend continuously,

The 'arm 12 extends from the free end of the top part 20 of the. book11) in the direction of the length ofthe supporting wire 2. and it isconnec gd tofthe part 20 by an edgewise bend 21 m the wire forming thesupport. The arm 12 xtends downwardly below the plane of the thp of thesupporting wire 2 t0 engage the wire Jon the opposite side thereof tothe side occupied by, the curved portion of the hook 10, or the sidearound which the hook 10 extends. p

In applying the. hook 10 to the wire :2. the cable support is turned andmanipulated to pass the arm 12 over the wire 2 in advance of the hook1t) and. thereafter. the hook 10 is engaged with the wire '3. The hook10 tits the wire 2 sulliciently loose to allow it to be rocked enough topermit the hook 11 to more under the wire 2 while the book 10 is beingapplied thereto. During and-after the application of. the hook -10 tothe wire 2. the hook 11 is moved l)c- Death the wire 2 in thedirectiolrof the arrow 30 by springing the loop or body 1) ol' thesupport until the free end of the hook 11 clears the side of the wire 2on which the arrow 31) is located: whereupon the hook I1 -is raised andengaged with the wire 2. as

illustratedin the drawings. while the loop or body portion 9 of thesupport is permitted to spring back to or toward its normal condition.\Vhen the book 11 is thus applied to'the wire 2. the loop!) is sprung inopposition to pressure of the hook tlL in the direction of the arrow 31.against the wire 2 and in opposition to pressure of the free end of thearm 12, in the direction of the arrow 32 against the wire 2].

surfaces of the parts 241 and the operation just described for its appliOne or more parts of the cable support areretained within the spacebetwm-utwo adjacent large diameters T of the supporting wire. 2 by thecngagement of the book 11 with the wire 2 atlone side-thereof and theengagement of the hook 10 and arm 12 with the wire 2 at the oppositeside thereof. As herein illustrated. the parts of the cable support,each of which :u'ethusheld between two adjacent large diameters 7, arethe parts 20. 21. 22 and .33 and the arm 12. the distance between the,upper aud lower J2 and the uppot and lower sltl'fw'es ot' the parts .21and Q3, respoflively, beingeuch less than the support from being movedalong the suplarge diameter 7 of the supporting Wire 2 v and the books10 and 11 each being hooked around the supporting wire 2 above and be-'the book 10 and arm 12 will co-operate to prevent the hook 11 from beingaccidentally disengaged from the wire 2. by requiring the loop 9 to besprung from the condition shown in the drawings for suchdisengagement. 1i J When a cable is drawn through the loop a of the support. in eitherdirection, any

tendency to move the cable support with it rclativelv to the supportingwire 2 will cause one or more of the parts :30, 21, "22, 23 and 12 toengage one or more of the shoulders l'ormed between the large and smalldiaualers T and H. re pectively. of the sup-J porting wire 2jadjacentthereto and prevent I the support from moving with the cable 13;

and. thereafter 'the further tendency of the cable [It to movethe cablesupport will tend to cant the hooks Ill and 11 and therebypressthe-upper and lower parts thereofinto tirm gripping engagement withthe upper and lower parts. respectively. of the supportingwvire 2. thegripping a ctiouthus effected incrcasmg 111 power as the tendency of thecable to move the cable support increases in power.

The relation of the parts ot thc cable'support to each other before anda l'ter the 'suppoi't is applied to the supporting wire 2 may bcisuchthat more or .less pressure is exerted against the supporting wire 2b)"the books 10 audit and arm 12 in the directions of thcavrows 3U. 31 andil-l. respectivw l as the cable support tends to resume a normalcondition after being applied to the supporting wire 2; and. while suchpressure is desirable to avoid line titiin" and to hold the parts of thecable support hrmly in place 7 upon the suplmrtlug wire and in constantremhness to perform their functions. It is not necessary in the actualwork of the parts either to retain the hooks l0 and 11 upon thesupporting wire 2 of to prevent the cable porting wire 2 with the cablewhen the cab is drawn through the loop 9 of the support in eitherdirection.

I claim as my invention:-
